202 THE INDIAN JOURNAL OF VETERINARY SCIENCE AND ANIMAL HUSBANDRY [ I, III
DECLINE IN MILK YIELD WITH ADVANCEMENT OF LACTATIONS.
The procedure adopted for this inquiry was to sort out the monthly milk yield
in each lactation along with the date of calving in each case. The latter was
essential in arriving at the exact number of days, the cow was in milk during the
first month of calving. It may be pointed out that it is the general practice at the
Pusa Farm to record the milk from the 7th day after calving, the days prior to that
being considered as the colostrum period. It is also the practice here to record the
lactation yield for ten calendar months, i.e., 304 days, which is the average lacta-
tion period in almost all the milch breed of cows. Hence the figures referred to in
this paper are in accordance with the above practice.
The total number of cases studied works up to 397 in all, a consolidated re-
view of the detailed analysis of which is given in Appendix B. The following Table
gives the monthly milk yield in different lactations.
